I was too quick to hit Send:
1) this is an array formula and needs CTRL+SHIFT+ENTER
2) the vector A10:20 has 11 elements while A1:J1 and A2:J2 have only 10 each
so use =SUMPRODUCT(--(A1:J1=TRANSPOSE(A10:A19)),A2:J2)

I think this is what you want
=SUMPRODUCT(--(A1:J1=TRANSPOSE(A10:A20)),A2:J2)

Hi Bernard,

That is indeed the situation that I require solving.


Cheers,

Can you tell us in words what you want?
Is it: to sum B values when corresponding A value matches anything in
A10:A20?

Dear all,

I wish to use a SUMIF(range, criteria, sum range) forumula utlising OR
for
the criteria, e.g.

=SUMIF(A1:J1,OR(A10:A20),B2:J2)

It would appear however that this does not work. Can you please point
out
the error of my ways, thank-you.


Yours in appreciation (as always),

Neil
